Frost is not going to suddenly blossom elsewhere, he may score more but he's going to be a role player where ever he goes. He simply doesn't have "it," that intangible quality that top players possess. TK isn't more talented than Frost, he's certainly not as big, but the difference on ice jumps out at you.
I think it's time to move on b/c he's not a good fit here, he's best on a finesse team. On a PO team, he's a 3C and won't get the same chances he got here. And he'll probably thrive in a sheltered role where he's not asked to do too much.
The problem here is expectations were too high and the team too thin, so he was asked to play a bigger role than he can handle. Some players rise to that kind of challenge, others are exposed.
The idea he was "ruined" is silly, he had two years that were about as much as you'd expect from a late 1st rd center (compare to Laughton and Poehling, both drafted ahead of him). He improved on defense, but he's not a high motor physical forward. He's a second tier finesse scorer. He's opportunistic, but doesn't drive play.
